use the list.sort() method to make sure the slots list gets sorted after an item is added.

Please help me

inventory.py 
class Inventory:
    def __init__(self):
        self.slots = []

    def add_item(self, item):
        self.slots.append(item)

class SortedInventory(Inventory):
    def add_item(self,item,):
        self.sort = sort
        super().add_item(item) 
        list.sort()
        return self.slots

class Inventory:
    def __init__(self):
        self.slots = []

    def add_item(self, item):
        self.slots.append(item)

class SortedInventory(Inventory):
    def add_item(self,item,):
        self.sort = sort👈#Error 1
        super().add_item(item) 
        list.sort()👈#Error 2
        return self.slots👈#Error 3

Take a look at Error 1, why did you create a variable? Take a look at Error 2, what is list here? think about it, list is basically referring to nothing here, so why did you use list.sort()?. The only LIST that's' available is self.slots. Try doing self.slots.sort().

If you need this code re-written, tag me or post back here, I'll make sure I can help you out but first try to apply these changes.
